I tried recordmydesktop from command line as it appeared the GUI frontend was using a lot of resources .......

Here is the output from the terminal ....  I did not bother specifying the sound device .....

Code: [Select]
[user@Dell ~]$ recordmydesktop -windowid $(xwininfo |grep "Window id:"|sed -e "s/xwininfo\:\ Window id:\ // ;s/\ .*//") -fps 15                                                         
Initial recording window is set to:
X:0   Y:51    Width:1680    Height:972
Adjusted recording window is set to:
X:0   Y:50    Width:1680    Height:976
Your window manager appears to be KWin

Xlib:  extension "Generic Event Extension" missing on display ":0.0".

When played back I still have approx 1 frame every 7 seconds.

I wonder if it has anything to do with running it on KDE4?

regards.

Thanks.  Yes I am on kde4 as well... maybe I will try it on another machine on kde3 or something and see if I get the same problem.

Although I do get more than 1 frame every 7 seconds.  It actually does not look choppy at all to me.
